Title:
MATERIAL AND METHOD OF DIFFUSION TRANSFER
Document Type and Number:
Japanese Patent JPS58169148
Kind Code:
A
Abstract:
A photographic silver halide material comprising a compound which is capable of being reduced by a silver halide developing agent at a rate slower than that of image-wise developable silver halide and in reduced state is capable of releasing a photographically useful group, characterized in that said compound corresponds to the following formula: wherein: R10 and R20 (same or different) (1) represent an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group or an aralkyl group including said groups in substituted form, (2) represent an aryl group including a substituted aryl group, or (3) represent a heterocyclic ring residue including such residue in substituted form, or R10 and R20 are ringclosed, either R10 or R20 containing a ballasting group conferring diffusion resistance to the compound in hydrophilic colloid media when penetrated by an aqueous alkaline liquid; L1 and L2 (same or different) represent a -SO2-; -NHCO-; -NHSO2-; -O-SO2- or group; p and q (same or different) represent an integer 0 or 1; Z represents an atom or an atom group which is electronegative with respect to carbon, and PUG represents together with Z a releasable photographically useful group.
